ROTARY TABLE MOUNTING Fon VEGETABLE PEELERS Murry G. McClung, Los Angeles, Calif. Application September 21, 1942, Serial N o. 459,210

4 Claims.

This invention relates to a vegetable peeler of the type set forth in United States Letters Patent No. 2,231,543 issued February 11, 1941, embodying an upstandingl cylindrical container iittedk with a rotary table, and more particularly pertains to improvements in the mounting of the rotary table and its driving mechanism. The subject'matter hereof is shown at least in part in myyco'mpanion application Serial Number 459,209 which has resulted in Patent No. 2,339,936 issued J anuary 25, 1944.

An object of the invention is to provide a mounting for the rotary table including a support for a rotary shaft on which the table is mounted extending through the bottom wall of the container embodying a construction whereby leakage of water from the container around and through the mounting will be eiectively prevented; it behighly desirable to prevent the water used in the peeling operation and which becomes fouled with dirt and peelings from working into the shaft bearings and from leaking onto the shaft driving transmission which is located beneath the container bottom wall.

Another object is to provide a construction whereby the assemblage of the mounting on the container andits association with the bottom wall thereof will be facilitated.

A further object is to provide a construction in the mounting wherebykthe bearing parts thereof are rendered easily accessible for removal and replacement and whereby wearing parts may be readily renewed so that the mechanism of the peeler may be economically maintained in order.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawings in which:

Fig. 1 is a view in vertical section, partly in elevation, of the vegetable peeler showing the invention as applied;

Fig. 2 is a horizontal section and plan view taken on the line 2-2 of Fig. 1 with portions broken away;

Fig. r3 is a detail in vertical section taken on the line 3--3 of Fig. 2 with parts shown in elevation;

Fig.f4 is a detail in section and elevation depicting the manner of initially positioning the mounting for the table bearing through the bottom wall of the container; Fig. 5 is a view in section and elevation similar to Fig. 4 showing the manner of sealing the joint betweenv the bearing mounting and the container bottom wall;

Fig. 6 is a Vview in side elevation of the vegetable peeler to which the invention is applied.

Referringto the drawings more specifically, A indicates generally an upright cylindrical container which is open at its ends and is tted with a removable cover.B which loosely seats on the upperend of the container and has a downwardly inclined central portion 'l leading to an opening 8 and which cover serves as a hopper through which articles to be peeled may be directed into thecontainer.,

Spaced upwardly from the lower open end of the container is an inclined bottom wall 9 from the lower portion of which leads a discharge spout I0 for carrying off wash water which is delivered to the container. Arranged in the container is a horizontally extending rotary table C carried on the upper end of a vertical shaft I l which extends through a' bearing housingA D projecting through the bottom wall 9 and which member is carried on a spider `E `located beneath the bottom wall 9. The legsl I2 of the spider have flanges I3 on and formed integral with the hub of their outer ends which abut and are secured to the inner periphery of thewall of the container apart from the bot-- tom wall 9 of the latter. The bearing housing D embodies an upstanding cylindrical portion I4 formed with a circumferential channel I5 providing the bearing supporting member with an intermediate portion I6 of reduced diameter. The bottom wall 9 is formed with an opening Il bordered by an upstanding flange I8 through which the reduced intermediate portion I6 of the bearing supporting member I4 extends. In initially assembling the bearing supporting member in relation to the bottom wall 9, it is inserted through the opening I1 and positioned as shown in Fig. 4 with a packing material I9 interposed between the flange I8 and the reduced portion IB of the cylinder I 4. The upper end of the flange I8 is then beaded inwardly over the packing material I9 as shown at 20 in Fig. 5. A split clamping ring 2I is thenpositioned around the flange I8 and is brought into tight encircling engagement therewith by means of a. conventional stove bolt 22 and its associated nut 23 engaging the usual ears 24 on theA ends of the split ring as shown in Fig. 2'. A ring 25 of plastic metal compound is then built up between the inturned margin 20 of the flange I8 and the shoulder 26 at the upper margin of the channel l5. 4A similar ring 21 of plastic metal compound is then built up between the lower mar- 30 comprises the conventional pair` of annular,`

raceways a and b with balls c interposed therebetween. The inner portion of the upper `annulus a underlies the shoulder 29 while the outerporti'on thereof underlies the lower end of the bushing 3| in spaced relation thereto to provide a space 3"| around the shaft immediately above the 'bearing 30. The upper portion of the shaft is encompassed by an elongated wearing bushing 3`| fitted in the upper portion of the :bearing housing D and projecting slightly above the upper end of the latter. A flange 32 on the upper end-portion of the shaft I overlies the upper end of the bushing 3| in close proximity thereto butspaced therefrom and carried `thereonlis a dis-k -33 having a downturned marginal apron 34 overlying the margin of the flange '3`2.a'nd the upper end portion of the bushing 3| so .as to span and seal the gap between the end `of the bushing 3l and the ange 32. The upper end of Ithe shaft is formed with a threaded stud '35 for screw engagement with the rotary .table C; the latter being formed on its underside with a threaded socket 36 for reception kof the stud 35. The screw threads of the stud 35 and socket 36 arespiralled in a direction opposite to the direction -of normal operative rotation of the shaft H kso that -rotation of the shaft in its forward `direction will tend to tighten the stud in-thefsocket. n

The space 31 is lprovided around the Asha-ft at the lower fend of the bushing 3| and just above the bearing 30 lfor reception of a packing and lubricating grease which is delivered #to thisspace and to spaces in the bear-ing communicating therewith through a lubricant supply tube -38 connecting with a passage 39 leading through the bearing vhousing D to the space 31. The grease receiving space 3-1 and passage v39 are located below the ybottom wall 9 of the container whereby the Vgr-ease may -be applied when need be from the exterior of the container.

The -lower end portion of the shaft |l| extends through a wearing bushing 40 removably housed in a sleeve 4| .seated in the lower end Eof the bearing vhousing D, which llower end of the shaft has removably fixed thereon a ,pulley wheel 42, the hub 43 of which forms Aan abutment for the lower end of the bushing 40 which projects through an .opening 44 in Vthe lower -end of the bearing housing. The sleeve 4-| seats Ona `flange 45 forming the margi-nvof the eopening V44. The upper ends of the bushing 40 and sleeve 4| terminate on a plane spaced a :short -distance above the lower end of the housing and remote from the upper end of Qthe latter; Vand for-m `a seat for .the llower raceway b of the lball bearing 30 and whereby the ball bearing is positioned close to but above the lower end 'of the housing contiguous the spider E. The wheel 4'2 is -engaged by a Ybelt 46 passing around the drive wheel 4F! of an electric motor 48 mounted :on ,the container A; the latter being Afitted with a Aface plate 49 carrying threaded 4studs 50 which extend through vside flanges 51| of the motor 43 and are engaged by nuts 52 to effect fastening of the motor on the housing.

Axed by screws 53 to the underside of the spider E is a transmission guard F embodying a top plate 54 which overlies the wheels 42 and 41 and their associated belt 46; the top plate being formed with an opening d through which the shaft extends and with an opening e through which the shaft of the motor 48 extends. A protective apron 55 depends from the margin of the top plate 54 which is arranged to lie close to but spaced from the belt 4B throughout the length thereof.

By the construction set forth, assemblage of 'the rotary table C and its mounting may be y readily accomplished, To effect mounting of the rotary table the shaft I| is initially attached thereto by screwing the threaded end stud 35 thereof into engagement with the correspondingly threaded recess 36 on the underside of the table with the flange 32 on the shaft abutting the disk 33 to Yhold the latter in place. T-he assembled bushing 40 and sleeve-4| are then positioned in the bearing housing whereupon the balllbearing 30 is seated on the bushing and sleeve. The bush ing 3| is then set in place in the bearing hous-` ing with a tight fit. The shaft .I3 carrying the table '|'2'is then put in .place by inserting the shaft through the bushings 3| and 40 to seat the shoulder 29 of the shaft on the upper and free raceway a of the bearing 30. The :pulley wheel 42 is then attached to the lower end of the shaft v|| in a conventional fashion as by a key 56 Iand set screw '51. When thus assembled the shaft will be .supported intermediate its `ends on ,a foot ball bearing and will be retained `in its upright position .by the bushings 3| kand -40 disposed on opposite sides of the ball bearing. .By this arrangement .the point of greatest wear in the :bearing .structure will be in `the bushings 43|,and 40 which may be easily removed and replaced.

By forming the seal between the `bearing housing and the container bottom wall asv set forth, leakage from the container at this Ipoint will .be prevented, and by the provisions of the clamping ring '2] the flange |'8 will be reinforced and tightly held against outward distortion such -as totloosen the packing and whereby the seal is rendered highly durable.

By :packing the bearing with a yheavy grease and providing .the protective Aapron 34 at the upper end of the upper bushing 3|, leakage vof water through the bearing will be effectively prevented.

While I have shown andy described a specific embodiment of my invention I do not limitv myself to the exact details of construction setforth, and the invention embraces such changes, :modications and equivalents of the parts 'and their formation and arrangement as come vwi-thin 1th purview ofthe appended claims.
